[jboss-user] [JBoss Messaging] - Re: Destruction/cleanup of temporary queues

[paduffy]

The following test client confirms that simply closing a Connection will not delete any created temporary queues.  Performed w/ JBM 1.3 and EAP 4.2.  This example requires the consumer be closed and the temp Q explicitly deleted to cause removal of the temp Q.  This conflicts with JEE JavaDoc, which states that closing the connection will remove temporary queues.

Further, if the connection is simply closed, the temp Q appears to be a permanent resource leak within the broker (confirmed w/ JNDIView).

Please advise.  If the answer is "move to 1.4", please confirm that this issue is resolved in 1.4...I am unable to find any info in the JIRA.
